What are router cutters for drilling?

Drilling router bits are designed for use with plunge routers, and can be used to perform the same tasks as some varieties of drill bit. 

Design

Flutes

Drilling router cutters predominantly use a two-flute design for a reasonably neat cut. Plug cutters are an exception, however, and use a four cutter configuration. 

Bottom cut

All drilling router cutters are bottom cut - they would not be able to drill holes otherwise! However, none of them are suitable for routing, as they are not designed to move around while cutting. This could easily break your bit.

Guides

Drilling router cutters do not require guides, as they are held in place by the router itself. As they are drilling in one spot, there is no need for them to move around.

Applications

The types of bit, or cutter, that are available for use with routers are mainly geared towards wood joinery. Even within these guidelines, each type of bit has its own specific use.

• Professional TCT & STC router cutters
